TPS3808G18-Q1 描述

The TPS3808 microprocessor supervisory circuits monitor system voltages from 0.4 V to 5 V, asserting an open-drain RESET signal when the SENSE voltage drops below a preset threshold or when the manual reset (MR) pin drops to a logic low. The RESET output remains low for the user-adjustable delay time after the SENSE voltage and MR return above their thresholds. The TPS3808 uses a precision reference to achieve 0.5% threshold accuracy for VIT ≤ 3.3 V. The reset delay time can be set to 20 ms by disconnecting the CT pin, 300 ms by connecting the CT pin to VDD using a resistor, or can be user adjusted between 1.25 ms and 10 s by connecting the CT pin to an external capacitor.
